I can't print a PDF file using Acrobat Professional 8.1.2 to an HP Laserjet 8100. The printer dialog shows the job and lights blink on the printer, but nothing is printed. I can print the same PDF file on the HP 8100 using Apple Preview. I can print the same file using Acrobat 8.1.2 on the HP Color Laserjet 5550 sitting next to the HP 8100. I just can't print to the HP Laserjet 8100 using Acrobat 8.1.2. I can also print to the HP 8100 using Acrobat 8.1.2 if I check the box "Print as image", but it is very slow in that mode. Does anyone know the answer to this one?

I have re-installed the HP printer drivers from HP. I have deleted and reinstalled the printers. All Apple and Adobe updates are current. I am using a Mac Pro with Mac OS 10.5.4.
